Exchanging Bart Tickets
At certain stations there are booths which allow you to exchange old tickets for a single ticket with the accumulated value. Does anyone know why they do not accept tickets purchased with a credit card?
The woman at the counter indicated that tickets printed with the letter "C" are tickets purchased by credit cards and cannot be used for exchange. I actually found a way around it by adding money in the ticket machines with a coin which removes the "C" from the ticket and converts it into a cash ticket. However, I'm still interested in finding out why credit card tickets are treated differently.
